  • Angled rotary tissue cutting instruments and inner members therefor having flexible couplings
    Patent number: 8029524
    Abstract: A flexible inner tubular member for rotation within an angled outer tubular member of a rotary tissue cutting instrument includes a distal end having a cutting element, a proximal end connectible with a powered surgical handpiece, and a flexible coupling between the distal end and the proximal end for transmitting torque to rotate the cutting element while conforming to the angled configuration of the outer member. The flexible coupling comprises inner, middle and outer spiral members, each formed of a flat strip of material, alternately wound in opposite rotational directions. The strips of material that form the inner and outer spiral members have a width intentionally and measurably different from the width of the strip of material that forms the middle spiral member.

  • Method and system for reconstructing aberrated image profiles through simulation
    Patent number: 8027813
    Abstract: A system and method of calculating estimated image profiles. The system and method includes providing lens characteristic data and performing simulation calculations for various levels of aberration components using the lens characteristic data. A response surface functional relation is built between selected variables of the lens characteristics, in particular the lens aberration components, and the Image Profile using the simulation calculations. Evaluation is then performed on the arbitrary specified aberration values of a lens in relation to the response surface functional relations to provide a calculated estimate of the Image Profile for the specified aberration values. A machine readable medium and exposure apparatus are also provided.

  • Paintball marker
    Patent number: 7997260
    Abstract: A pneumatic paintball marker has, for example, a sleeve that controls the passage of air through the longitudinal barrel or opening within the marker. By sequentially filling separate chambers defined within the opening and the sleeve, the sleeve is able to translate axially through the opening in a sequential manner. When the sleeve is in a forward position, air is caused to be released through the barrel, propelling the paintball. A sear member engages the sleeve and prevents it from inadvertently moving to a forward position. Air filling the chambers returns the sleeve to the loading position.
